I. Installation & Operation
NOTE: The EXP-EMG-EXT-LE6-4L is designed to be surface mounted to flat surfaces such
as walls.
I. Installation
Mounting for this fixture is achieved via
mounting tabs located on the back side
of the light.
The EXP-EMG-2L-LE6 explosion proof
emergency self-testing LED fixture is NOT
a factory sealed fixture. Operators will bring
their own rigid conduit to a junction box and
complete their connects. Cap off any hubs
that are not in use.
Both battery legs must be connected
together. This prevents the battery from
draining during storage and transit. DO
NOT CONNECT HIGH VOLTAGE TO
BATTERYLEGS.
II. Operation
1. ApplyAC power to the light. The LED
indicator will turn RED.
2. See wires labeled for connections.
3. Use appropriate methods for wiring
within hazardous areas following all
appropriate NEC codes. Consult an
electrician if unsure.
4. In the event of power loss, the fixture
will illuminate all lights automatically.
Once power is restored, the lights
will turn off and the batteries will
charge.

Instruction Manual
Do not attempt installation until you are familiar with all warnings, precautions, and procedures outlined within
this instruction sheet.
WARNING:
READ CAREFULLY BEFORE INSTALLING FIXTURE. RETAIN THESE INSTRUCTIONS FOR FUTURE
REFERENCE. CRITICAL SAFETY INSTRUCTIONS:
•To avoid the risk of fire, explosion, or electric shock, this product should be installed, inspected, and
maintained by a qualified electrician only, in accordance with all applicable electrical codes.
To avoid electric shock:
•Be certain electrical power is OFF before and during installation and maintenance.
•Luminaire must be supplied by a wiring system with an equipment grounding conductor.
To avoid burning hands:
•Make sure lens and housing are cool when performing maintenance.
To avoid explosion:
•Make sure the supply voltage is the same as the luminaire voltage.
•Do not install where the marked operating temperatures exceed the ignition temperature of the
hazardous atmosphere.
•Do not operate in ambient temperatures above those indicated on the luminaire nameplate.
•Use proper supply wiring as specified on the luminaire nameplate.
•All gasket seals must be clean.
•Before opening, electrical power to the luminaire must be turned off. Keep tightly closed when in
operation.
•Use only UL listed components suitable for Class I Division 1, Groups C & D and Class II Division 1,
Groups F & G installation.
•All threaded connections must engage five full threads.
Refer to the luminaire nameplate for specific
classification information, maximum ambient
temperature suitability, and corresponding
operating temperature (TCode).
MOUNTING & WIRING
1. Mount the enclosure to surface in a location
that can support the load. Use single bolt to
provide rotation when mounting.
2. Loosen the two set screws on the bracket to
adjust vertical position as necessary.
WIRING
1. Remove the front cover module by
loosening the single set screw and rotating
counter-clockwise.
2. Pull field wiring into module. This light
connects to the corresponding wires on the
main unit.
3. Close all unused conduit entries with
conduit plugs. To ensure water-tightness,
lubricate conduit plugs with lubricant before
installing, and secure wrench-tight with at
least five (5) full threads engaged (42-52 ft.-
lb. for 3/4” plugs, and 58-68 ft.-lb. for 1”
plugs).
4. Connect supply wires to luminaire wire
leads (or terminal blocks) using methods
that comply with all applicable codes.
Tighten all electrical connections.
5. Close cover module, making sure that all
wires are safely inside driver. Tighten
captive closing screw.
6. Turn power on and aim light.

MAINTENANCE
1. Perform visual, electrical, and mechanical inspections on a regular basis. The environment and
frequency of use should determine this. However, it is recommended that checks be made at least
once a year. We recommend an Electrical Preventive Maintenance Program as described in the
National Fire
2. Protection Association Bulletin NFPA No. 70B: Recommended Practice For Electrical Equipment
Maintenance (www.nfpa.org).
3. The lens should be cleaned periodically to ensure continued lighting performance. To clean, wipe the
lens with a clean, damp cloth. If this is not sufficient, use a mild soap or a liquid cleaner such as
Collinite NCF or Duco #7. Do not use an abrasive, strong alkaline, or acid cleaner. Damage may result.
4. Visually check for undue heating evidenced by discoloration of wires or other components, damaged
parts, or leakage evidenced by water or corrosion in the interior. Replace all worn, damaged, or
malfunctioning components, and clean gasket seals before putting the luminaire back into service.
5. Electrically check to make sure that all connections are clean and tight.
6. Mechanically check that all parts are properly assembled.

INSTALLATION, OPERATION & MAINTENANCE DATA SHEET
TYPE "EYS" HORIZONTAL / VERTICAL SEALING FITTING
SUITABLE FOR CLASS I, DIV. 1 & 2, GROUPS A, B, C & D
AND CLASS II, DIV. 1 & 2, GROUPS E, F & G HAZARDOUS LOCATIONS.
Sealing fittings are installed in conduit runs to minimize the passage of gases, vapors, or flames from one portion of the electrical
installation to another through the conduit, as well as to prevent precompression or "pressure-piling" of vapors or gases in conduit systems.
NOTE: Seals should be made only by experienced, careful persons in strict compliance with these instructions. Even slight variations can
cause serious field problems. Read directions completely.
DIRECTIONS FOR INSTALLATION
Using the drawings and chart at the right as a guide, install the sealing
fitting into the conduit system. Refer to the National Electrical Code,
Articles 501-5 and 502-5 for the regulations covering your specific
application.
Pull the conductors (wires) through the conduit system.
Using Packing Fiber, build a dam at each conduit hub (except upper hubs
in vertical seals.) Use a wooden stick to force the wires apart, and pack
the fiber tightly around all wires. The dam must be tight and strong
enough to keep the liquid sealing compound from leaking out before it
sets up. The completed dam should be even with the conduit stop.
Use the included Sealing Compound with these fittings. The sealing
compound is mixed with water at the rate of three (3) parts of sealing
compound to one (1) part of water by volume. See chart to determine
the amount of compound required for a specific fitting. Use a clean
mixing vessel for each batch. Sprinkle the sealing compound into the
water while stirring, until a thickpaste is formed. Continue mixing for AT
LEAST THREE (3) MINUTES. The proper consistency is just fluid
enough to pour SLOWLY , like thick gravy, from an inverted container,
NOT WATERY. Do not mix more material than can be poured in 15
minutes. Discard any material that becomes too stiffto use. Never
attempt to restore workability by stirringinmore water.
After the compound is mixed, slowly pour it into the sealing fitting to the
required level. Make sure that the wires are well separated, so the
compound completely surrounds them. Pour slowly to avoid trapping air
bubbles in the compound. Immediately wipe any spilled compound from
conduits and threads, and close the fitting with the close-up plug. Make
sure the plugs are tight.
Initial set of the sealing compound will occur within thirty (30) minutes.
However, the compound requires a minimum of 8 hours above 32° F to
develop sufficient strength to withstand explosion pressures.
*NOTE: These fittings are approved for use only with Killark "SC" Sealing Compound.
